and useful Improvements in Devices for Fastening Roofing :Sh.ingles,' of which the following is a specification, reference being had to the accompanying drawings. Our' invention relates to devices more especia-lly useful in fastening so-calle'd f,pre-' or 'curlin pared shingles, to the surfaces of roof structures designed for their support. Such shingles ordinarily consist of a base of felt or paper usually impregnated with a suit-.

able water-proof preservative and coatedon one or both sides with a weather resistant compound of asphaltum or the like.- On account of the comparative lightness of the shingle material and a certain degree of inherent flexibility, the exposed or projecting.

ends of the shingles, after being laid in the usual way heretofore, were, under windy weather conditions, often lifted to an extent suflicient to cause dislodgment or tearing of the shingles. On the other hand, warping of the projecting shingle ends through irect exposure to extreme changes of-temperature, resulted in a condition quite as. unsatisfactory, greatly marring the appearance of the roof. were specially true in instances where the shingles were laid diagonally and consequently with comparatively greater areas of their surfaces exposed.

The main object of our invention is to overcome the various difiiculties abovepointed out, and this desideratum we attain in a fastening device capable of positively holding and retainingthe depending ti or butt end of a diagonally placed shing e of one course, and having incorporated means whereby it may be anchored to the supporting structure of the roof, and, at the same time, serve to secure contiguous corners of ad acent shingles of an underlylng or subjacent course.

Other objects and attendant advantages of our invention will become readily apparent from the detailed description which follows of a number of different forms in which our invention is capable of embodiment;

These conditions Fig. II is a perspective View, on alarger' scale, of thefas tenin device in its simplest form, and showing 1n dotted lines, slight configurative variations; and

Figs. III and IV are views similar to Fig.'

II, showing other possible modifications of the device.

The simplest form. of our invention shown in Fig. Hand indicatedcom rehensivelysby the numeral 1, may be brie y described as preferably formed of a single piece of stout laterally extending 'fianks 3-3 which terminate in perpendicularly disposed prongs. 44. These prongs are sharpened as by chamfering as. indicated at 5, 5, so that they may be readily driven, into the supporting structure of a roof ina manner to be presently explained. If desired, in meeting the exigencles of practice, the flanks 33 maybe disposed either. in acute or obtuse an lar relation to the cross bar 2 as suggeste in dotted lines instead of in the right angular relation illustrated in full. I

In building a roof, the shingles indicated by the letter S in Fig. I, are laid a. course at a time in a diagonal placement with lateral corners of adjacent shingles in close proximity or abutting as shown in said figure. Either after laying each course, or incidentally to the la ing of the individual shingles,

a fastening evice 1 is, in accordance with plished byany type of tool suitable to the pur ose, an ordinary hammer serving very wel in lieu of any other. After one course of shingles has been laid and fastened in the 'wire and as comprising across bar 2 with Y manner just described, a succeeding .course is super osed upon the first, the depending tips or utt ends of the shingles being engaged beneath the horizontally disposed cross bars 2 of the fastening devices 1 before bein in their turn secured as already underespecially observed that only the cross bars 2 of the fastening devices are ex osed, while all other portions are overlappe so that the possibility of water entering the pierced regions of the shingles is entirely precluded. The fastening device of Fig. III differs from the previous one only in the flattening of the flanks 33 at the region of their mergence with the prongs 4, 4 as indicated at 6, 6. This revision afl'ords heads of expanded area or greater contact with the shingle surfaces and at the same time facilitates driving.

The last modification shown in Fig. IV is identical with the form of Fig. I except for a sli ht raising or ofi'setting of the cross bar relative to the plane of the flanks 3 to compensate for the thickness of the shingle corner or tip which is to be engaged beneath the same, and to allow the flanks 3, 3t0 rest directly and securely against the surfaces of the shingles which are penetrated by the prongs 4=4.'. This variation may be attained by an additional bending of the wire of the fastening device as indicated at 77. Obviously, if desired, either or both the features. characterizing the modifications of Figs. III and IV may be incorporated in the type shown in Fig. I.

Strip shingles notched to simulate shingle' ends, may obviously be secured and their exposed tips or ends engaged for retainment in a manner similar to that herein-described in connection with the laying of separate or individual shingles, the advantages procuradapted to be secured to the supporting structure.

, 2. As a new article of manufacture, a shingle fastening device comprising a horizontal cross-bar adapted to overlie the butt end of diagonally laid shingles, flanks extending laterally from the ends of said cross-bar in a slightlydepressed plane to compensate for the thickness of the shingle and adapted to be concealed beneath the latter, and prongs integral with the free ends of said flanks whereby the device is secured to the supporting structure.

In testimony whereof, I, the said ANDREW L. BELL, have hereunto signed my name at Buffalo, New York, this fifth day of Feb- In testimony whereof, I, the said FRANK A. BROWNE, have hereunto signed my name at Philadelphia, Pennsylvania, this 5th day of February, 1923.
